C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.
Answer: C.Food
Explanation: In the process of photosynthesis, the chloroplasts in the cell make the food- sugar/glucose-. they do this by collecting the sunlight, water, and carbon dioxide, making the food. Any food they don't end up using is then converted to oxygen.
Answer:
Look down!!! ;)
Explanation:
In a human karyotype, autosomes or “body chromosomes” (all of the non–sex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). However, chromosome 21 is actually shorter than chromosome 22.
Hope this helps!! ;)
Answer:
Glucose is a sugar that many plants, animals and fungi use for energy. In plants, glucose is produced as a result of photosynthesis. Plants need the energy glucose provides in order to grow and reproduce. ... Without glucose, plants would not have the energy necessary to grow, reproduce or carry out cellular respiration.

Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
